Match the species given in Column I with the shape given in Column II and mark the correct option.

Column I

Column II

A. Its partial hydrolysis does not change the oxidation state of the central atom.

B. It is used in modern diving apparatus.

C. It is used to provide an inert atmosphere for filling electrical bulbs.

D. Its central atom is in sp3dhybridisation.

1. He

2. XeF6

3. XeF4

4. Ar

           A            B            C            D

1.       1            4             2            3

2.        1            2             3            4

3.        2            1             4            3

4.        1            3             2            4


 


Hint: Xe hybridization in XeF4 is sp3d2.
(A) Partial hydrolysis of XeF6 does not change the oxidation state of the central atom. The reaction is as follows:

XeF6 + 2H2O → XeO2F2 + 4HF

(B) Helium is used as a diluent for oxygen in modern diving apparatus because of its very low solubility in blood.

(C) Argon is used mainly to provide an inert atmosphere in high-temperature metallurgical processes (arc welding of metals or alloys) and for filling electric bulbs. 

(D) The hybridization of Xe in XeF4  is sp3d2 hybridization.



Hence, option third is the correct answer.
